Maxwell's demon in the quantum Zeno regime

In the original Maxwell's demon thought experiment, a demon makes continuous measurements on a system of hot and cold reservoirs, building up a thermal gradient that can later be used to perform work. As the demon's measurements ...

Faster and less-invasive atomic force microscopy for visualizing biomolecular systems

High-speed atomic force microscopy (HS-AFM) is an imaging technique that can be used for visualizing biological processes, for example the activity of proteins. Nowadays, typical HS-AFM frame rates are as high as 12 frames ...

Pure optical detection of spikes for the ultimate brain machine interface

(Phys.org)—Brain-machine interfaces (BMIs) are basically gimmicks. The reason you don't hear so much about them these days is because, in the fullness of time, significant tangible benefit to a user has flat out failed ...
